UNLABELLED Atherosclerosis is an inflammatory disease, and ischemic stroke is one of its most common and devastating manifestations. Proinflammatory cytokines play a key role in the progression of the irreversible ischemic lesions. The presence of anti-inflammatory mediators may prevent secondary ischemic injury. OBJECTIVES 1) To assess the relationship… (More)
AIM We analyzed data from 71 patients with chronic granulomatous disease (CGD) with a confirmed genetic diagnosis, registered in the online Latin American Society of Primary Immunodeficiencies (LASID) database. RESULTS Latin American CGD patients presented with recurrent and severe infections caused by several organisms. The mean age at disease onset was… (More)
BACKGROUND Surgical treatment of hemorrhagic complication in schistosomal portal hypertension in our hospital is an esophagogastric devascularization procedure with splenectomy. Infectious risks and immunological alterations imputed to splenectomy may have significant importance. To minimize the consequences of spleen absence, the use of subtotal… (More)
BACKGROUND Patients with atopic dermatitis frequently present recurrent infections by pyogenic bacteria or by intracellular microorganisms, suggesting an immune disorder. OBJECTIVE Laboratorial investigation of phagocyte activity and chemotactic response by neutrophilic polymorphonuclear and mononuclear phagocytes in the peripheral blood of patients with… (More)
We describe a patient with common variable immunodeficiency who three times presented an anaphylactic reaction after intravenous immunoglobulin administration. These reactions were attributed to the total absence of IgG 2, 3 and 4.
Three patients with atopic dermatitis, one boy and two girls, aged between 6 and 17 years, presented eczematous skin, pruritus, scarifications, lichenification and a family history of atopy. During exacerbations, the patients sought emergency care and were prescribed oral corticosteroids for a period of approximately 15 days. Initially, the patients… (More)
Five patients with atopic dermatitis, three males and two females, aged 2 to 17 years, had positive reactions to air allergens (Dermatophagoides pteronyssinus and/or farinae). All the patients suffered from severe recurrent dermatophytosis that responded poorly to antifungal treatment. The results of immunologic evaluation by laboratory tests were normal,… (More)
The total complement and C3 and C4 components serum levels were assessed in vitro in forty children suffering from severe and moderate protein-calorie malnutrition in the 2 to 5 year age group. Twenty well-nourished children of the same age were as a control group. The results in the three group showed no significant differences.
UNLABELLED Infections and malnutrition remain the main causes of infant mortality in developing countries. In protein-calorie malnutrition, immunologic responses are affected, which often facilitates infections. However, the presence of asthma and allergic rhinitis are not commonly recognized in malnourished individuals. The aim of this study was to… (More)
A 21 years old male suffered from repeated furunculosis in different regions of the body over the last two years. This coincided with the start of professional activities in hospital surroundings. The purulent secretions all showed growth of Staphylococcus aureus. All laboratory tests were normal except for a decrease of the neutrophil phagocytic ingestion… (More)
